Doble, whose length of contract has not been specified by the promoted League One club, is Graham Turner's fourth signing of the summer, following the arrival of midfielders Asa Hall (Oxford United), Aaron Wildig (Cardiff City) and defender Darren Jones (Aldershot).

There is also speculation that Turner might bring in another midfielder, Cheltenham Town's Luke Summerfield, son of former Shrewsbury player and assistant manager Kevin.
